Tammy Baldwin now has a three point lead over her GOP challenger in the battle to win one of Wisconsin's Senate seats, according to a poll sponsored by a Democratic political action committee.

The Democracy for America poll, which queried nearly 1,000 people last week, showed Baldwin leading Tommy Thompson, a former Republican governor of Wisconsin. The poll also showed Thompson's favoribility numbers dropping, with 53% of voters reporting a negative view of him.

Should Baldwin win in November, she would be the first LGBT person to serve in the U.S. Senate.
